Great conditioner, but the packaging could be better
Size: 33.8 Fl Oz (Pack of 1)
I really liked this conditioner. It has a lovely scent and leaves my hair feeling soft, smooth, and shiny. My hair is straight, with an oily-prone scalp and drier ends, and this conditioner does a great job moisturizing the ends without making my roots feel heavy. It helps with detangling and makes my hair look healthy and well cared for. I would definitely recommend this product. My only complaint is the packaging. Just like the shampoo, the cap is peeling, which is disappointing. For the price, I expected better quality packaging. ... show more

Best conditioner for fine hair!
Size: 33.8 Fl Oz (Pack of 1)
The absolute best conditioner for fine hair. My hair is easily weighed down by products, but this conditioner leaves my hair feeling healthy, conditioned and it smells absolutely amazing. I use the Sebastian Dark Oil Shampoo in combination with this conditioner and it is *muah* chefs kiss. Highly recommend! ... show more

Best conditioner I've found! Keeps frizzies away and gives hair shine all the while making it soft.

From coars hair to soft

I have coarse hair and this conditioner works so well to smooth out my hair and keep it frizz free. I use it with the matching shampoo for best results.

Sample size
Size: 1.7 Fl Oz (Pack of 1)
Excellent product but it is a very tiny size. Almost like sample size. I had to return it and buy a larger size.
